Every year since 2004 Extendahome have held a fishing tournament and camping weekend at Mungo Brush camping ground, near Hawks Nest on the mid north coast of NSW. There is always an average attendance of 120-150 people, mainly being Extendahome team members, sub contractors and suppliers and their families. It is always a fun weekend and we hold a charity auction to raise money for worthy charities. Since 2010 our special charity has been Ronald McDonald House, Newcastle. This is a wonderful organisation managed by Ross and Rohan Bingham – through their tireless work they help make the lives of families with sick children a little bit easier while they have kids in hospital. We at Extendahome are proud to help this worthy cause in some small way – most years we manage to raise and donate approx. $25,000 to the cause. The last few years Ronald McDonald himself has attended much to the enjoyment of all the kids at Extendacup!

I felt like my dream had come true. This is a house that we can leave our sons with confidence so it was an investment as much as it was a lifestyle change.
