It's the ground where the legends of Raper, Gasnier and Langlands were born, now the Sharks could take the extraordinary step of moving home games into the territory of arch rivals St George Illawarra.

The Herald understands the long-awaited refurbishment of Cronulla's leagues club has prompted discussion whether to shift some of their fixtures 10km up the road to Kogarah's Netstrata Jubilee Stadium, the traditional home of their long-time enemies.

No exact start date has been confirmed for the next stage of Cronulla's vast redevelopment, which has included residential units adjacent to PointsBet Stadium. But construction on the leagues club, which forms part of the eastern grandstand, is expected to begin in 2020.

It has forced Sharks officials to consider drastic contingency plans for their home fixtures, which includes shifting either some or all of their games away from PointsBet Stadium during the redevelopment. The construction is expected to take up to two years.
