Injury hit Australia have called up winger Lachie Turner and flanker Matt Hodgson as squad replacements for their Rugby World Cup campaign in New Zealand.

The pair are joining the squad as replacements for winger Drew Mitchell and number eight Wycliff Palu.

Mitchell and Palu have succumbed to hamstring injuries, with Mitchell breaking down in Saturday's 68-22 final pool game win over Russia in Nelson.

A scan confirmed Sunday that Mitchell will not return in time to participate again in the tournament and he is expected to be sidelined for six weeks after suffering a grade one strain to his left hamstring.

Palu left for home last week but Australian team management held off naming a replacement in order to check on the Wallabies’ requirements heading into the knockout rounds.

Turner and Hodgson were both involved with the Wallabies earlier in the year, as members of the original 40-man Australian squad, and then as part of the squad which contested and won the Tri Nations.

Turner, 24, has played 14 Tests for the Wallabies, the most recent of which was as a replacement during last year’s record 59-16 win over France in Paris.

Hodgson, 30, has played six Tests, with two caps earned this year during the Tests against Samoa and South Africa in Sydney.

Team officials said the two replacements will join the Wallabies in Wellington late Monday
