Would two people on 80-90k be enough to live comfortably?

Me and my wife are both nurses in the UK and looking to emigrate over in the not too distant future. We have 2 children and would be looking to live somewhere coastal, ideally between Sydney and Melbourne somewhere.

Would this level of income be enough to afford a decent standard of living for the 4 of us? To afford a decent place to live, all essential items, and activities for the children? Maybe a trip back to the uk once a year? We aren’t too fussed about eating out and stuff. But we enjoy day trips as a family and the children like to do sports activities. We would probably need 2 cars. We would hopefully get a 491 visa and PR at some point. Q

Any insight off people who live there would be great!

Thanks
