Both courses, which are only four or so kilometres apart, experienced delays although the Royal Portrush suffered the most, a delay of more than eight hours putting the championship well behind schedule.
The majority of the now 282 man field has yet to even start round two after which the leading 64 players will advance to the match play phase.
Andrew Schonewille, who led the Australians after day one with an opening round of 68 at Royal Portrush, had played only three holes when play was eventually called for the day. He dropped an early shot at Portstewart and is now in a share of 17th position.
Torquay (Victoria) golfer, Ben Eccles, started with a rush at Royal Portrush with birdies at his opening two holes before a bogey at the 3rd but through three holes he has advanced his cause to be in 26th position which he shares with NSW's Cameron Davis who has yet to get round two underway.
The disappointment for the Australian contingent came when Victorian D.J. Loypur was disqualified after his opening round of 71.
