I think in 1998 was a turning point when Pippa had gone and she moved out of the caravan park standing on her own two feet. And also just before that as she was suddenly the oldest foster kid there ten years after being the youngest.
Then in 2000 was pushed to the front of the show in the non wedding.
Then in 2004 by moving back to the caravan park now as head of the house hold.
All significant moment for her character.
Having said that the time in between the non wedding and meeting Flynn. So late 2000 early 2001 was an odd time for her. She just floated for ages. It’s like they wasn’t sure where to go with her for a while. Getting engaged to that Luke guy, then that random moment with Harry and the pun Tom Nash. And then a fling with Brett Egan. Everything was so half hearted
regarding sally and Alisa. Yes, it true that a lot of time during her teenage years we didn’t see them together much. But there’s a few lovely scenes of them in the very early years and I remember when Alisa was lost after the diner hold up they had a nice scene with Alisa visiting sally.
