One particular park in Perth tried to oust the on site home people and gave them notice to move so they could develop the land, some moved but some formed a class action against the park owners and won the right to stay there until their long term leases ran out.
The park owners lost the court action and decided they would have to keep running it as a caravan park for awhile until they could let all the leases expire. Unfortunately some of the park home people had already been forced to move as their leases had expired.
