Australia's ruthless pursuit of Olympic hockey gold has been laid bare by four high-profile omissions from the Kookaburras and Hockeyroos teams to play in Paris.

Sixteen-strong squads were confirmed in Perth on Monday, men's coach Colin Batch relegating Tokyo Olympians Tim Howard and Daniel Beale as well as luckless forward Nathan Ephraums.

Defender Howard has played 137 times for Australia, Beale has 241 caps while Ephraums (71 caps) was also cut ahead of the Tokyo Games.

Ephraums and Howard will at least travel to France as two of three reserves to be called upon in case of injury or withdrawal, unlike Hockeyroos striker Rosie Malone who has missed out altogether.

The Gold Coast talent was shortlisted as one of five for the world's player of the year gong last year and scored twice in the Hockeyroos' run to the quarter-finals in Tokyo.

But the 26-year-old has paid the price in a team searching for more regular avenues to goal after she scored just once in 15 Pro League fixtures this season.

Malone (33 goals in 114 games) appealed her non-selection to the independent, government-backed National Sports Tribunal but had her case dismissed on Friday.

An asterisks remains on the squad list though, Malone indicating her intention to elevate the matter to the Court of Arbitration for Sport in a last-ditch attempt to win selection.

Coach and two-time gold medal winner Katrina Powell and independent chair Rechelle Hawkes, who was part of all three Hockeyroos gold medal teams, make up part of the selection panel.

Powell said her phone call to Malone "went as expected" and said that the decision was strictly performance-based.

"Ability, talent, combinations, versatility; this group will give us the best chance," she said.

"These athletes sacrifice a lot and we've got a strong depth of talent."

The Hockeyroos won gold in 1988, 1996 and 2000 but have missed the podium since, crashing out in a quarter-final loss to India after an unbeaten pool stage in Tokyo three years ago.

They finished mid-table with an 8-7 record in the latest Pro League season that was dominated by the Dutch.

The Kookaburras will enter Paris as Pro League champions, having cast the net wide since a shootout loss to Belgium in the Tokyo Games final denied the side a second Olympic gold.

But coach Batch will blood just three Olympic debutants, Jake Harvie, Ky Willott and Corey Weyer, named alongside evergreen Eddie Ockenden, who at 37 will become the first Australian hockey player to feature in five Olympics.

"We haven't selected some quality players and we have acknowledged that within the group and the immense work that they've put in," Batch said.

"He's (Ockenden) like a good bottle of red wine, isn't he?

"And I know he wants a bigger goal and that's not just being in the team, he wants success in Paris."

The Hockeyroos have drawn Argentina, Great Britain, Spain, USA and South Africa in their pool, while the Kookaburras will take on Belgium, India, Argentina, New Zealand and Ireland.

The Hockey competition will begin on July 27 at Yves-du-Manoir Stadium, the only venue used for the 1924 Paris Olympics to remain in use 100 years later.

In 1924 it hosted the opening ceremony, athletics, cycling, equestrian, gymnastics, tennis, football, rugby and modern pentathlon.
