Days of torrential rain have forced competitions ito cancel entire rounds, move venues and reorganise games.

Illawarra Coal League shifted their minor semi-final from Parrish Park to Dapto Showground on Saturday night (7pm), with the Canaries now taking on Thirroul on home turf.

Group Seven hope to play their scheduled qualifying and elimination finals, despite the deluge of rain on the South Coast.

The Group Seven general manager Jim McAuliffe said Sunday's elimination final between Warilla and Nowra Bomaderry is expected to go ahead at Cec Glenholmes Oval.

A decision will be made on the Gerringong and Kiama qualifying final is expected to be made on Thursday.

"As long as we don't have too much rain, we're hopeful of going ahead as planned," he said.

"We've got some contingencies in place just in case for the Gerringong game, but at this stage we believe we will be right.

"The grounds themselves have held up pretty well."

Football South Coast will make a formal decision on the Illawarra Premier League on Thursday morning but the final round remains in severe doubt.

The last round of AFL South Coast on Saturday has been called off, but officials are hoping week one of the Division 2 finals can go still ahead.

Severe weather left South Coast officials to determine no play would be possible.

Minor premiers Wollongong Lions will take on premiers Wollongong Bulldogs in the major semi-final on Saturday week, with third-placed Northern Districts to meet Kiama Power in the elimination semi.

The final round washout is a blow to the Bulldogs, who had the bye last weekend and face a three week break heading into the clash against the Lions.

However, Saturday's qualifying final and elimination final in Division 2 remains on.

West Street Oval at Nowra is scheduled to host both Division 2 semi-finals, with Wollongong Bulldogs to take on Bomaderry in the Qualifying Final (12.15pm), followed by Ulladulla Dockers against Wollongong Lions (2.10pm).

Given the continuing wet weather a decision on the fate of both matches will be made on Friday or Saturday.

The winner of the Qualifying final takes on minor premiers Figtree Kangaroos on Saturday week for a spot in the reserve grand final.

The winner of the Elimination Final face the loser of the Qualifying Final.

Finally, the cancellation of the final round in Division One had no influence on the top four finals.

Meanwhile, the opening weekend of the Illawarra baseball semi-finals is set to be washed out.

If no play is possible fourth-placed Berkeley Eagles will be eliminated for a second straight year due to wet weather.

Eagles are due to face Wests Cardinals, but third-placed Cards would advance to the preliminary final, while minor premiers Northern Pirates would move straight into the grand final if their clash against Dapto Chiefs (second) is called off.

A decision on the fate of baseball will be made on Friday.
