The NSWRU and QRU do not trust each other and are always looking out for their own interests, a fact which the ARU/RA exploits to maintain the status quo in national rugby union. But one thing which is guaranteed to unite the NSWRU and QRU against the ARU/RA would be any move by the ARU/RA to reintroduce a professional provincial rugby team to WA. The two heartland unions fought for 12 years to shut down professional rugby in WA and they would not simply roll over and let the ARU/RA reintroduce professional rugby to WA. So in the unlikely event that SANZAAR agrees to a fifth Australian Super Rugby team at some time in the future, there's Buckley's of that team coming to WA (Western Sydney Force, anyone?).
The Queenslanders may be pissed off because the 2019 Bledisloe has gone to Perth (and the 2020 Bledisloe has gone to Melbourne) but the simple fact is that the ARU/RA could not find anyone else dumb enough to pay them $5 million for the "privilege" of hosting either test, especially no-one in Queensland.
The ARU/RA must love outfits like the WA Government/Tourism WA who appear to enthusiastically hand over millions of tax-payers' dollars in sponsorship of sporting events with questionable tourism value. I can't wait to see how much the ARU/RA will be able to squeeze out of the WA Government/Tourism WA in sponsorship of Wallabies vs Tier 2 union tests in Perth post 2019.
The new World Rugby global calendar for 2020-2032 has increased the number of games which Tier 1 unions must play against Tier 2 unions; there will be a minimum of 110 Tier 1 vs Tier 2 tests in the 13 year calendar period, and while a lot of those tests will be played when Tier 1 teams tour Tier 2 nations (e.g. England and France will be touring the Pacific Islands), the SANZAAR unions have committed to hosting Tier 2 teams in the July international window. This means the ARU/RA will have to find hosting stadiums and sponsors (i.e. gullible state governments) who are willing to pay for the privilege of hosting those Wallabies vs Tier 2 tests. I don't think Wallabies vs Georgia tests were quite what Victoria had in mind when it handed over x million dollars to the ARU/RA in return for 6 Wallabies tests in Melbourne during 2018-2025 (where "x" may be between 15 and 20).
