The club did not have to wait long to win their maiden First Grade title and start a history of strong and respected local rugby league teams.

1946 saw the Port Kembla District RLFC win the Clayton Cup, presented to the Country Rugby League First Grade club with the best season record.

Port Kembla has produced five Australian representatives in Noel Mulligan, Frank Johnston, Charlie Hazleton, Ian Moir and John Simon.

A host of Port Kembla coaches have also made State and Australian teams including Ron Costello, Graeme Langlands and Brian Hetherington.

The Black's last senior premiership was achieved in 2010 when the team coached by Jason Sullivan and captained by Jon Koot defeated Mount Kembla in the VBR Cup Grand Final 22–10.

In 2007, Keith Lulia became the first Port Kembla junior since John Simon to progress to the NRL, debuting with the St George Illawarra Dragons in a 22–20 win over newcomers, the Gold Coast Titans.
