Our community is one of the best in Adelaide and not just because of its beautiful beaches, proud industrial and maritime heritage, tourism attractions and successful sporting clubs. Our community is such a great part of South Australia because of its people. Residents of the Lefevre Peninsula and the western suburbs truly are the best going around: neighbourly, compassionate, proud of their heritage and always looking out for those in our community who need a hand. To be considered a worthy representative to this place is a great honour, indeed. Deputy Speaker, I can assure you that I will be working conscientiously to do my best on their behalf.
