My Margaret O'Halloran married Thomas Wall in Co Clare and settled in Brisbane. James Wall and Margaret Canny did settle in Victoria around Wyndham / Werribee area. As far as the O'Keeffe's are concerned I think my ggg-grandmother, Bridget O'Keeffe remained in Co Clare. I'm not even sure if John & Bridget Wall were alive when the 3 brothers emigrated here.
