Aboriginal recognition campaigner Jackie Huggins is urging indigenous leaders to leave their egos at home when they attend a summit on Monday.
Around 40 leaders will meet with Prime Minister Tony Abbott and Opposition Leader Bill Shorten in Sydney to thrash out a form of words for a referendum on Aboriginal recognition in the constitution.
"When the leaders are in the room and realise the seriousness of this ... hopefully they will put their egos at bay in order to get our people and the Australian people across the line on this referendum," Dr Jackie Huggins, a spokeswoman for campaign group Recognise, told Sky News on Sunday.
There's cross-party backing for recognition, as well as strong support in opinion polls and from the Aboriginal community itself.
Aboriginal recognition campaigner Jackie Huggins believes it would be "catastrophic" if a referendum to recognise indigenous people in the Australian constitution failed.
