Dyer due a break after mammoth Wales season
Written by I Dig SportsDyer says the squad are disappointed they could not finish the international campaign on a high, with defeat in Melbourne representing a ninth successive Test defeat.
The latest loss also means Wales' 55-year wait for a win against the Wallabies in Australia will continue.
"It is frustrating for a lot of us going on from the result in Sydney," said Dyer.
"We were in the game at 60 minutes and then letting go of it.
"It is the same thing happening. For the last two weeks we have been working hard, non-stop in training.
"We wanted this win, to make history as a team and go back to Wales with a win but annoyingly we haven't got it."
Dyer demonstrated his class with a superb second-half solo try against Australia but it could not inspire a Wales comeback.
"It is trying to get that fluidity into the game and that worked well for us," said Dyer.
"It's about that ball movement, getting width into our game and the ball into players hands and trying to create something.
"It would be nice to do it a little bit more. Even though we have not got the results in the last two weeks some of the stuff we have put together has been good.
"If we can put an 80-minute performance together, keep our discipline and not give away easy tries, we would have been able to get the two wins comfortably and prove to others we will be a very good team.
"It is just those little errors that didn't help us throughout the games."
