Next year England warm up in the (English) Summer before the Ashes with a single test against ZIM & then a 5 test series against India. (May - Jul). Australia warm up with 2 tests against WI ( Jun).
Problem for Australia is that other than Eng & WI there aren't any other test teams bar Ireland that play cricket in Australia's Winter. England & WI every 4 years leaves 2 years out of 4 without (Australian) Winter cricket.
The solution would be to play test cricket in FNQ/Darwin but I guess there's no money in it. If money wasn't an issue they could have tri nations test series in Northern Australia with AFG,ZIM,IRE,BAN etc
