High end router available in Australia for OpenWRT?

Guys,

After two routers to run OpenWRT on - they will only be performing the wireless AP functionality - handing off to a captive portal - all routing/firewalling is performed by another box.

Trying to find something reasonably current that is availabe in Australia - does not need to be bleeding edge just something with reasonable hardware support (from the vendor) and good OpenWRT prospects going forwards
