Nicholas grabbed one of the final two spots available at qualifying venue Fairhaven Golf Club in Lancashire.
The 58-year-old was a Thalidomide baby; one of an estimated 20,000 people worldwide born with stunted limbs due to a morning sickness drug that was taken off the market in the early 1960s because of links to birth defects.
Nicholas will join other Australians John Wade, Paul Archbold and Nicholas Rob as qualifiers in a field which will also include Australasians Peter Fowler, Stephen Leaney, David McKenzie, Peter O’Malley, Michael Campbell and Greg Turner.
The event is one of the most prestigious senior major championships and is also an official PGA Tour Champions event.
