Two cricketing heavyweights will clash this afternoon for a place in Sunday's World Cup final against New Zealand.
Co-hosts Australia are the favourites to win, but their fans may be outnumbered by Indian supporters at the Sydney Cricket Ground.
The 46,000 seat ground is expected to be packed with confident Indian supporters.
But Australian captain Michael Clarke said his team would not be affected.
"I think it's fine, we've played in India a number of times, and they out-support s there as well."
The sides are fierce rivals, and have won six of the ten previous World Cups between them.
India are undefeated so far in the tournament, but have only ever beaten Australia once in Sydney in one-day internationals.
And they have not managed to beat Australia during their four-month tour of the country.
But Indian star batsman Rohit Sharma said that did not matter because his side was now playing a different brand of cricket.
Meanwhile, the Black Caps have been given the day off, having arrived in Melbourne last night.
They will watch this afternoon's game knowing they face a tough task on Sunday whoever wins.
NZ fans risk flying for Sunday's game
New Zealanders wanting last minute flights to this weekend's Cricket World Cup final in Melbourne said they were struggling.
Tickets to the match have sold out but organisers say disappointed fans of the losing team in today's other semi-final might put their tickets up for sale depending which side wins today.
Some New Zealand fans have gambled hundreds of dollars on flights in the hope they can get match tickets.
Yesterday, Air New Zealand announced it would put on an extra return flight on Saturday from Auckland to Melbourne. JetStar has confirmed it is not putting on extra flights this weekend.
