McGrath told the Fiji Sun that he has applied for the position.
“Yes, I did apply,” McGrath said from England over the weekend.
Applications for the post left vacant at the expiry of the contract of Ben Ryan closed last Friday.
The Fiji Rugby Union board is expected to vet the applications this week.
McGrath is a former professional rugby league player who developed a successful career as a coach first in rugby league and then rugby union.
He is an education graduate who has written and lectured extensively in coaching skills.
