Two reports about Heath's funeral yesterday: http://www.news.com.au/perthnow/story/0,21598,23184887-948,00.html http://news.bbc.co.uk/1/hi/entertainment/7236169.stm There is no mention of any protests from Westboro Baptist Church (the location in Australia probably helped there).
They protested at his earlier memorial service in America, they got a (tiny) mention in our paper over here. They were held off by lots of security though, so couldn't get anywhere near the venue.
