Flynn returned from the Sultan Azlan Shah Cup in Malaysia last weekend with a hamstring injury which needed surgery and is back in Perth. 

A major setback for Ogilvie, it came as the Kookaburras lost the final of the Azlan Shah Cup to Great Britain 4-3. 

"I came straight back to Perth with the team so I could get a scan on my hamstring which tore off and will need surgery to reattach it," Ogilvie said on his return. 

“It looks like I will be out for at least six months and maybe longer, just depends how well it recovers.”

Ogilvie will miss the World League semi-finals in South Africa, trans-Tasman series with New Zealand and the international festival of hockey in Bendigo in November. 

It is also extremely unlikely he will return in time for the World League finals in India and December.

Having played 47 games and scored 13 goals for Australia, Ogilvie’s next major focus is on the Commonwealth Games, held on the Gold Coast in April. 

As the dominant force among Commonwealth nations, the Kookaburras have never been beaten in the sport’s history at the Games.

They’ve won five gold, since being introduced in 1998. However, England and New Zealand loom as threats to breaking the stranglehold next year.

The English are ranked seventh and New Zealand eighth, while the Australians have been knocked off top spot by rising power Argentina.

The Australian women’s team, featuring Gerringong’s Grace Stewart, is currently ranked fourth in the world.

Stewart was part of Australia finishing third at the junior World Cup, played in Chile last year.

Meanwhile, former Kookaburras striker Kieran Govers returned to his club Albion Park in the Illawarra hockey league to score a goal in the 3-0 win over Wests Illawarra last weekend.

Govers has been playing in the Dutch national league with Den Bosch.
