Cameron is 14 year old who used to ride a BMX bike in the bushes after school. There is a panther bike club who ride bikes on a ramp made on Penrith council property but the ramp is owned by panther bike club and they use the ramp on just weekends and there's no security interfering the use of ramp.One day Cameron was performing stunts without helmet on the bike at the ramp and got head injuries 1. Who breached the duty of care either panthers club or Penrith council ? 2. Who owns duty of care towards Cameron 3. Any defences advised
