Health authorities confirmed at least 12 cases of the new variant have been recorded in the sunshine state.
The recombinant was first detected by the Institut Pasteur in Paris, France, according to international science not-for-profit GISAID.
Health authorities are saying there is no evidence these new strains will cause more sickness or counter the effects of current COVID-19 vaccines.
The NSW Health weekly COVID-19 report indicates the state recorded one case of Deltacron and one case of an Omicron and multi sub-variant combination.
While the cases were first reported yesterday, NSW Health said they were not identified this week.
