Four-time major champion Davies said Kingston Heath is the best course she will play this year.
'I like Sunningdale (in England) but I think this is a better version of Sunningdale,' said Davies, who won the New South Wales Open in Sydney last week.
Sunningdale will host the women's British Open later this year.
'I'm trying to think of the courses I would prefer to play,' she added. 'The only ones I can come up with are St. Andrews and Royal Lytham. This rates as my third favorite course I have ever played.'
Webb, the defending champion, said it was good that members of the women's tour had a chance to play at Kingston Heath.
'The men get to play on such courses fairly often but we don't get that opportunity as much. I think everyone is excited to be here this week,' said Webb, who won the Australian Open for a third time at Royal Sydney last year.
Kingston Heath has been set up long for the women at 6,651 yards.
'I don't think really low numbers are going to win around here,' Davies said. 'It's so well bunkered and people are going to drop shots.'
The routing and order of the golf course, originally set by architect Dan Soutar in the 1920s, have been changed for the tournament. The five finishing holes are all within easy reach of the clubhouse, and the sixth hole will play as the 18th.
