Typically under HIC rules, a referral must be supplied with a specific referral period in months, or the word "indefinite".
This is how all referrals from GPs to medical specialists work, and I would assume this is how DVA will require referrals to be done for podiatry from now on.
Convincing a GP that an indefinite referral is appropriate may be a more cumbersome challenge though - they might assume you are trying to 'milk' the system...
