NSW's bowlers were deprived of a chance to drive home the Blues' advantage in the Sheffield Shield match against Tasmania when rain ruined much of day two.
The Tigers were 1-79 in reply to NSW's 8(dec)-449, a deficit of 370 runs, when stumps were drawn early on Sunday at the SCG.
Rain and bad light forced the players to come off the ground in the middle session that led to an early tea, and no further play was possible.
With further showers predicted on Monday, the third-placed Blues face a race against time in pursuit of victory.
Experienced opener Alex Doolan (nine) was the only Tasmanian batsman to fall, getting a leading edge off seamer Gurinder Sandhu to Nick Larkin in gully.
Captain George Bailey (34no) and Beau Webster (31no) have put on 61 for the second wicket and looked relatively untroubled on a flat deck.
Earlier, Moises Henriques (131no) and Trent Copeland (41) put their foot down as NSW overcame the exits of captain Peter Nevill (five) and Steve O'Keefe (duck) in the first two overs of the morning to add 57 to their overnight total in just 11.5 overs.
Tom Rogers (4-88) was the pick of the visitors' bowlers.
