nah mate - they were known as Newcastle KB United.
KB was a beer brand many young uns wouldn't have heard of.
They started in '77, '78 in the NSL, fell apart in '84.
While they often struggled to compete at the very top of the league Newcastle were regular mid table finishers and their only honour was in 1984 when they travelled to
Melbourne Knights and won the national league cup 1–0, playing as the newly formed
Newcastle Rosebud United. The goal was scored by Derek Todd.
KB United's NSL licence was taken over by Northern New South Wales State League club
Adamstown Rosebuds in 1984 after the collapse of Newcastle KB United. Rosebuds renamed themselves
Newcastle Rosebud United while they played in the NSL. They were excluded from the NSL at the end of the 1986 season when it was re-organised and returned to the NNSW League.
It would be another 5 years before Newcastle had another representative in the
National Soccer League, this time via the newly formed
Newcastle Breakers FC.
