They still lost – 16 years since they last won a series in England. However the obvious difference is that they have managed to win tests (even ones which aren’t dead rubbers), whilst England are looking like they might be on the way to their 3rd whitewash in 4 visits since they first won the urn back on home ground.*
Not that trying to replicate Aussie conditions for practice in England would be likely to help much – and nor would getting England players to play domestic Aussie cricket (were that even possible given the modern international merry go round). The problem is far earlier in the system.
* I think I’d take a non-whitewash as a moral victory
