Queensland's must-win one-day clash with Tasmania at the Gabba was washed out without a ball being bowled.
Queensland picked up two points along with the Tigers.
The third-placed Bulls (15pts) had been desperate to chip away at leaders Victoria (19pts) and No.2 outfit South Australia (18pts) with a win over Ricky Ponting's Tigers (11pts).
The stage had been set for Queensland to pick up from their three straight one-day wins before the Big Bash League break, with Bulls captain James Hopes returning from a hamstring complaint.
However, officials called off the game with up to 300mm expected to inundate south-east Queensland as ex-tropical cyclone Oswald moves down the coast on Sunday.
Queensland hope to next host Western Australia at the Gabba on February 2 - weather permitting - before playing the final qualifying one-dayer against Victoria at the MCG a fortnight later.
The Sheffield Shield clash between NSW and WA also had day four washed out.
Just 10 overs were bowled on Sunday due to persistent rain, with umpires declaring at 5.37pm that no more play was possible.
With WA resuming at 8-211, with a second-innings lead of just 109 runs, the Blues were confident of getting a result before they were confronted by a soggy outfield at Blacktown International Sportspark.
On six occasions the covers were removed by groundstaff, only to be put back moments later as the drizzle persisted before players took to the field.
No wickets fell and the Warriors added just eight runs through Ashton Agar (34no) and Jason Behrendorff (7no) to finish 8-219.
NSW claimed first-innings points thanks to classy half-centuries from Test hopefuls Steve Smith (72) and Moises Henriques (71) that gave them a 102-run first-innings lead, but the missed opportunity to claim the maximum six points from the game will irk them.
The Sunday washout also denied players a final chance at pushing their Test cases, with the squad for next month's four-Test tour of India expected to be announced on Thursday.
Blues captain Stephen O'Keefe, considered an option to be picked as the back-up spinner to Nathan Lyon, did his chances no harm with match figures of 8-102 to take his season tally to 17 wickets.
The two sides will face off in the one-day arena at the SCG on Wednesday, while WA's next four-day game is against Queensland at the Gabba starting on February 4 and NSW travel to Tasmania to take on the Tigers from February 6.
