In theory you can have issues with a candidate who would do better on the final count getting knocked out earlier, and thus a voter could be strategic by preferencing higher the person who is likely to get more preferences.

An example of this was Fannie Bay in the NT 2024, when Labor would have won a clear Labor vs CLP count, but they came third and the Greens came second. Labor preference flows to the Greens were weaker, so the CLP won. A voter who most cared about not electing a Lib should've put Labor above Greens.
But in practice it's very hard to judge who is likely to benefit from such an imbalance, particularly in an election like this.
The best advice to deal with this problem is 'number every box', or at least if there are 2 standout progressives make sure all the progressives give them both a number.
