KEY POINTS:
A last-minute visa hitch has forced a Melbourne Ethiopian refugee to wait one more day to be reunited tomorrow with four of his children he hasn't seen in a decade.
Jemal Ambo fled Ethiopia in 1998, leaving behind his six children, then aged 1, 2, 3, 5, 7 and 9. Two years later his wife also fled, taking their son, 4.
In 2003, the three were granted a refugee visa to Australia. The oldest son is missing.
