Lions Australia: Australia’s Largest Service Club Organisation With over 1,200 clubs and 25,000 members, Lions Australia is the nation's most diverse and active service organization. For over 75 years, we have been the "boots on the ground" during bushfires and floods, the pioneers in medical research—including the development of the Bionic Ear and the Cervical Cancer vaccine—and the champions of local community projects. Our unique "100% Rule" ensures that every dollar raised from the public goes directly to the cause, with all administrative costs covered by our members. At Lions, we don't just fundraise; we roll up our sleeves and serve.
