AGA membership is based on the standard financial year (1 July-30 June period) and subscription renewal invoices will be issued at the beginning of each membership period for payment strictly within AGA's normal trading terms, ie 30-days. Non-payment of membership fees within the 30-day period may result in an "unfinancial member" status and, if applicable, remove any entitlement to discounted Annual Renewal Fees for that membership year. Where necessary, AGA will issue a supplementary invoice to cover such differences.
Applications lodged part way through a subscription period must be supported by payment of a relevant annual membership fee (refer table above).
