What about having a double-hop VPN - the phones first VPN to a colo'd 
router in the Phillipines, which then VPNs back to Australia? This 
separates the carrier for the the local tails from your international 
routing. Or have the SIP connections terminate at the colo host, and then 
trunked back over IAX2 or SIP. Not sure which would be better for latency.
