Tasmania's Jackson Bird-led pace battery bowled out NSW twice inside five sessions to clinch an upset JLT Sheffield Shield win at Bellerive Oval.
The ladder-leading Blues were all for 184 following on after lunch on day four as the Tigers claimed a ten-wicket victory.
Fringe Test quick Bird took seven wickets for the match to keep his name in the minds of national selectors.
The win was even more impressive given wild rain wiped out day one's play entirely.
Resuming at 2-50 on Wednesday morning, NSW lost six wickets in an extended opening session.
Bird (4-34) found edges from Nic Maddinson and Ed Cowan to start the collapse.
He was ably assisted by young quicks Tom Rogers (3-32) and Sam Rainbird (2-30) as NSW crumbled to 8-124 at lunch.
Former Test wicketkeeper Peter Nevill (70) offered some resistance in a 90-minute stand with tailender Doug Bollinger as the pair soaked up time with rain approaching.
Nevill's biggest knock for the Shield season ended when part-time medium-pacer Jordan Silk snapped up a sharp caught-and-bowled catch.
Silk had earlier put the Tigers in the box seat with a ton in their first innings of 4(dec)-392.
Test discard Matthew Wade smacked an unbeaten 72 late on Monday.
"It was the best batting I've seen from the group since I've been here," Tigers first-year coach Adam Griffith said.
"We've done a lot of work over the last month on our defensive work and that showed.
"The fact the ball was nipping around as much as it was but we got through it, is a clear indicator we're on the right track."
NSW mustered 208 in reply before being sent back in.
They eventually levelled the overall score, forcing Tasmania into a second innings pursuit of one run.
Silk crunched a boundary to give the Tigers their second win of the season ahead of a two-month Shield break.
