Tasmania will be searching on Tuesday for their first win at the final day of netball's national championships.
The 19-and-under state side will take on the ACT and the 17-and-under faces Northern Territory in the seventh and eighth playoff matches to avoid finishing last in the tournament.
The ACT only just won the earlier 19-and-under battle 42-41 in Brisbane.
It was one of the side's two single-point losses after going down 37-36 two days earlier to the Northern Territory.
The Territorians were all over Tassie's 17-and-unders two days earlier following a 38-23 victory.
The Tasmanians looked condemned to the do-or-die encounters on the back of two emphatic losses in the fight for fifth place.
Western Australia were on top from the outset to run out comfortable 51-34 winners against Tasmania's 19-and-unders on Monday.
That was despite Hayley McDougall and Ruby Barkmeyer again combining well in the goal circle.
McDougall has shot 112 goals over eight matches at 14 apiece and is ranked third in the tournament for total goals at a strong 83 per cent.
But the Tasmanian midcourters struggled to stop the flow of the ball into the tall West Australian shooters.
Tasmania's 17-and-unders showed improvement in a 37-24 loss to Queensland.
The last time the two teams met, the home side got over them by 22 goals.
Tassie's defence worked hard to turn the ball over, creating more scoring chances.
Centre Hannah Lenthall worked drove the ball down court well while Hayley Older impressed at wing defence.
