So I thought I'd update what the front yard looks like now that the dead tree, bougainvilleas, palms and other stuff has been removed:
While we could and did do a lot ourselves, we resorted to paying some nice people to remove the palms. They certainly earned their money that day and I'm glad we paid people to do it. The replacement plants are mainly banksias, with a hakea planted in the front corner (behind the succulent in this photo). At least when these grow up they should provide a good habitat for native animals that wander around.
