Well Fran and Pete, you've given me something to think about. I'm going to wait untill you hear from the Wirrpanda Foundation Elle. It will be interesting to hear about Heath's involvement.
I'm not for 'doing things in Perth' because I feel his family have indicated (strongly, in my opinion) that they want to be left in peace. But donating money to a local charity is certainly a good idea, especially if it's a charity that Heath supported.
