Task: Question Understanding
Input (English): Passage: The Melbourne Storm played two marquee games at the MCG in 2000. This was the first time that they had played outside of their normal home ground of Olympic Park Stadium which held 18,500 people. Their first game was held on 3 March 2000 against the St. George Illawarra Dragons in a rematch of the infamous 1999 NRL Grand Final. Dragons player Anthony Mundine said the Storm were not worthy premiers and they responded by running in 12 tries to two, winning 70–10 in front of 23,239 fans. This was their biggest crowd they had played against until 33,427 turned up to the 2007 Preliminary Final at Docklands Stadium which saw Melbourne defeat the Parramatta Eels 26–10. The record home and away crowd record has also been overhauled, when a match at Docklands in 2010 against St George attracted 25,480 spectators. Their second game attracted only 15,535 spectators and was up against the Cronulla Sharks on 24 June 2000. Once again, the Storm won 22–16.
Question: What year did the Melbourne Storm play in front of their biggest crowd?
