Disability pension, for the purposes of service pension and income support supplement, means:

• a pension paid for incapacity from war caused conditions, or peacetime, peacekeeping or hazardous service caused conditions (other than a war widow's or orphan's pension); or
• temporary incapacity allowance; or
• any other payment in respect of incapacity or death resulting from war or war-like operations in which the Crown has been engaged [usually paid by another Commonwealth country].

A service pension is an income support payment broadly equivalent to the social security age and disability support pensions. It may be paid once a veteran or partner has reached the nominated age or is incapacitated for work.

Veterans' Entitlements Act 1986.
