While Australia won the last test I feel the decision to keep the same squad for final two squads is a disgrace. It is a total dereliction of their duties to keep players in the squad who are clearly failing to meet the minimum requirements.

Both the Marsh brothers belong nowhere near the squad they should have been dropped. 
Aaron Finch is not an opener, he is fighting hard but why is he being sacrificed? It almost seems they do not want a good opening partnership so that Warner can be brought straight back into the side as a kind of saviour to the opening position. 
Handscomb does not have the right technique to be successful, he needs to go at work on playing a way that lets his talent be shown at test cricket.

India have not be afraid to add to their squad after Shaw was ruled out for the whole series and Hardick Pandya proved he has recovered from injury, yet the Australian selectors have stayed with their own personal favourites despite them being failures at test level.

It was clearly time to bring in some other batsmen, Burns and Patterson would have been my choice while dropping Marsh and Handscomb and putting Finch in the middle order.
Drop Mitch Marsh from the squad entirely. A quality all rounder would be great to have in the squad but that is not Marsh and there is not another one available. The only reasonable option is to go with 6 batsmen and 4 bowlers. Lyon can bowl long spells and take wickets so the fast bowlers only need to cover one end for large periods of innings. Head can bowl a few overs if needed as well.

So lets get rid of the selectors and bring in some who do not think having the surname Marsh or being able to open in the fake cricket shorter forms of the game are qualifications to be selected and pick on merit. Also being part of a winning team should not be considered when a player does nothing to contribute to the win.

Time to say goodbye, Trevor Hohns, Mark Waugh, Justin Langer and Greg Chappell, 

And while we are sacking people perhaps sack Graeme Hick as batting coach. We need a coach who can instil fight and discipline into the batsmen, something which was notably absent from the hugely talented Hick's career as a flat track bully.
