Turns out the agent at SYD refused to short-check so everything got tagged to JFK. However bags have to be physically picked up at SFO to clear customs before "transferring" to the domestic leg. Mum says Dad held on and wouldn't let the "helpful" guy take the bags from him to put on the conveyor belt for connecting flights. When I got to SFO that evening I did tell the agent at check in that our bags would not be on the JFK flight with us. Didn't seem to be a problem.
