DVA Aggravation Claims Explained: When Service Makes an Existing Condition Worse

If you had a condition before you joined the ADF, or before a deployment, and military service made it worse, you can claim through DVA. This is called an aggravation claim, and it is one of the most underused pathways in the DVA system.

DVA received 101,157 claims in FY 2024–25, 13% higher than the previous year. The average claim now contains 4.1 conditions, up from 2.6 in 2022. Many of those additional conditions are aggravation claims that veterans did not realise they could lodge.

Many veterans assume that a pre-existing condition disqualifies them. It does not. Every Statement of Principles contains two sets of factors: clinical onset factors (the condition started because of service) and clinical worsening factors (the condition existed already but service made it materially worse). The worsening factors exist specifically for this situation.

What counts as an aggravation claim

An aggravation claim applies when you had a condition before or during service that did not arise out of service, and service activities materially contributed to making it worse.

• You had mild asthma before joining the ADF, and exposure to dust, fumes, or chemicals during service made it significantly worse.
• You played rugby as a teenager and had a knee injury before enlistment. Years of infantry service with loaded marching aggravated the knee to chronic pain and restricted movement.
• You had mild lower back pain before a deployment. The physical demands caused measurable worsening that persisted after return.
• You had a mental health condition before service (childhood trauma, pre-existing anxiety) and the stressors of military service materially contributed to it becoming significantly worse.

How clinical worsening is defined

Clinical worsening is not the same as a temporary flare-up. It means a permanent or sustained deterioration that is measurable and documented.

• A measurable increase in severity compared to the baseline before the aggravating factor. Increased pain, reduced range of motion, new neurological symptoms, higher impairment rating, or progression visible on imaging.
• Persistence beyond the aggravating period. A temporary increase during a field exercise that resolves within a week is not clinical worsening.
• Distinct from natural progression. DVA will consider whether the worsening would have occurred regardless of service. The service contribution needs to be shown as separate from the natural trajectory.

How worsening factors mirror onset factors

In most SoPs, the clinical worsening factors are near-identical to the onset factors. Same thresholds, same exposure requirements, same timeframes. The difference is they apply to a condition that already existed.

For thoracolumbar spondylosis (SoP No. 13 of 2023 RH): Factor 9(13) is onset — lifting 100,000 kg cumulative. Factor 9(31) is the equivalent worsening factor — same 100,000 kg threshold. Same evidence, different legal basis.

Every SoP also includes one worsening-only factor: inability to obtain appropriate clinical management. If you had a condition during service and couldn’t get proper treatment (remote posting, deployment, no specialist access), this factor captures the resulting worsening. It is the most underused factor in the entire SoP framework.

What DVA accepts liability for

When DVA accepts an aggravation claim, it accepts liability for the entire condition as it now presents, not just the portion attributable to service. Once accepted, your permanent impairment points are based on your current presentation. You are not penalised for having had the condition before service. DVA’s combined MRCA acceptance rate sits between 75% and 86% at the condition level. Aggravation claims assessed under the Reasonable Hypothesis standard benefit from a lower threshold of proof, meaning properly prepared claims have a strong chance of acceptance.

This means a veteran who had mild back pain before service and now has severe thoracolumbar spondylosis after 15 years of infantry work receives the same impairment assessment as a veteran whose back was fine before service.

Evidence you need

Baseline evidence

• Enlistment medical records showing a noted condition or abnormality.
• Pre-deployment medical assessments.
• Civilian GP records from before enlistment.
• Earlier imaging showing the condition at a less advanced stage.
• If no formal baseline exists, the absence itself can be useful — the inference that service caused the worsening is strong.

Evidence of the aggravating factor

Same evidence as an onset claim: service records, incident reports, medical treatment during service, buddy statements, and documentation quantifying the exposure.

Evidence of worsening

• Specialist report explicitly comparing current presentation to pre-service baseline and attributing the worsening to service activities.
• Current imaging compared to earlier imaging showing progression.
• Medical records documenting increasing symptoms and escalating treatment during or after the aggravating period.

Addressing natural progression

The specialist report should state something like: “the degree of degeneration observed is greater than expected for a person of this age and exceeds what would be attributable to natural progression alone, consistent with the physical demands of military service.” This directly counters the natural progression argument.

DVA reduced the number of medical forms required for claims from 210 to 84, and from 658 pages to 183. This simplification means less paperwork for aggravation claims, though the quality of your specialist report matters more than ever.

Common mistakes

• Not claiming at all because of the pre-existing condition. The worsening factors exist precisely for this situation.
• Claiming onset instead of worsening. If DVA’s records show the condition existed before service, claiming onset will fail. Claim worsening from the outset.
• Not establishing a baseline. Without evidence of what the condition looked like before, DVA has no reference point.
• Ignoring the “inability to obtain appropriate clinical management” factor. If military medical care was inadequate, this factor applies to every SoP.
• Not getting a specialist report that addresses worsening specifically. A generic “related to service” report isn’t enough. The report must compare current presentation to baseline and attribute the worsening to service.

Conditions where aggravation claims are most common

• Musculoskeletal conditions. Pre-service sports injuries, minor back problems, knee issues worsened by years of military physical demands.
• Mental health conditions. Childhood trauma, pre-existing anxiety worsened by operational stressors, workplace bullying, or military sexual trauma.
• Hearing conditions. Mild pre-service hearing loss or tinnitus worsened by military noise exposure.
• Skin conditions. Pre-existing solar keratosis or skin cancer risk worsened by years of outdoor service in Australia’s UV environment.

Musculoskeletal conditions are the most frequently claimed category through DVA. According to DVA’s processing data, the number of conditions per claim has risen from 2.6 in May 2022 to 4.1 in January 2026. This increase reflects veterans claiming related and secondary conditions, including aggravation claims, that they previously left on the table.

How aggravation interacts with your overall claim strategy

Aggravation claims are not second-class claims. They produce the same outcomes: accepted liability, permanent impairment assessment, compensation payments, and DVA health care. They contribute to your combined impairment score in the same way. A veteran with aggravated conditions accumulates points toward Gold Card eligibility at 60 points, SRDP, and all other threshold-based entitlements.

Frequently asked questions

Can I claim through DVA if I had the condition before I joined?

Yes. Every SoP contains clinical worsening factors specifically for pre-existing conditions made worse by service. A pre-existing condition does not disqualify you.

What’s the difference between clinical onset and clinical worsening?

Clinical onset is when the condition first appeared. Clinical worsening is when a pre-existing condition got measurably and permanently worse. Different factor sets, same evidence thresholds.

Does DVA pay less for an aggravation claim?

No. Permanent impairment compensation under MRCA is based on your combined impairment score at the time of assessment. The maximum weekly PI rate for warlike/non-warlike service is $431.84 at 80 impairment points. Your rating is the same whether the condition arose during service or was aggravated by it.

What if my condition wasn’t noted on my enlistment medical?

If it wasn’t documented before service, you may be able to claim onset instead. If DVA’s records show it existed beforehand, claim worsening. If no baseline exists, the absence of prior documentation can support either pathway.

What does “material contribution” mean?

Service played a real and meaningful role in worsening the condition. It doesn’t need to be the primary or only cause. If military service was one of several contributing factors, that’s enough, provided the contribution was more than trivial.

Can I claim aggravation for a condition that would have worsened anyway?

Yes, but the evidence needs to show service contributed beyond natural progression. A specialist report addressing this point directly is essential.

What is the “inability to obtain appropriate clinical management” factor?

A worsening factor in every SoP covering situations where you had a condition during service and couldn’t get proper treatment. Applies to deployments, remote postings, and inadequate military medical care. Doesn’t require physical thresholds — just evidence of needed treatment you didn’t receive.
