This was the second time the two have met WA Opera stars, after two singers last year visited their home at Nulsen Disability Services in Maddington for morning tea and a surprise performance.
Nulsen has been the Opera in the Park charity partner for more than a decade, with volunteers shaking donation tins and handing out programs in exchange for a gold coin donation at each performance.
Murphy, who has played the piano from a young age, takes weekly lessons and rehearses at every opportunity.
She is passionate about performing, regularly visiting other Nulsen homes to play for residents and staff.
Last year, she played to a large audience at the National Australasian Society for Intellectual Disability (ASID) conference in Fremantle.
She said meeting professional opera singers and playing for them made her feel special.
�I was very happy to play some of the songs I practice at piano lessons on the grand piano,� she said.
The charity partnership between Nulsen and WA Opera aims to find synergies between the arts and health sectors through discovering shared values.
