Looking for Tongan Artist June Egan

I am looking for a artist named June Egan her Tongan name was sune?  June did tapa cloth in her paintings by pounding inner bark of the paper mulberry tree against a flatten log with a wooden mallet using a brown dye called tongo.  I have 4 of her art works now I am trying to locate some more.  June had a show in 1977 at LeMaroi Gallery in which she sold sixty of her art pieces during one month showing.  She is Australian born I believe.  I would appreciate any information you may have in the comment section below.  Diana Leffler
