Australian Reservists can parade with Canadian Reserve units under the Reserve Forces Foreign Service Agreement (RFFSA), signed between Canada and Australia. In short, the Reservists must be qualified to the operational functional point (OFP) which, in Canada, is DP1. Requests are usually made to accommodate Reservists who find themselves in the other nation by virtue of school/work or spousal school or work commitments. Pay, LDA etc are paid by the sending state. TD and associated training costs (ammo, rations, quarters) are paid by the host nation.
The reverse, a Canadian "going south", is also possible. To be eligible, the Reservist must apply through their chain of command. A host unit should be contacted to ensure that the incoming Reservist has a position while in Canada. If a host unit cannot be located (or the member doesn't know where to start) Director Reserves can help.
RFFSAs also exist between Canada and the United Kingdom and, recently, the United States.
