Tributes have been flowing in on social media for the well-loved veteran, from the Hunter region in NSW, who was believed to be the oldest to participate in the Sydney Anzac Day march this year.

A member of the Merewether Hamilton Adamstown RSL Sub Branch, Mr Carpenter served in the 2/4th Australian Infantry Battalion and saw action around the Mediterranean and New Guinea.

"He will be missed by his fellow members of the RSL and we extend our condolences to his family and friends," RSL NSW said on social media.

"At the going down of the sun and in the morning, we will remember them. Lest we forget."

Merewether Mackerals, where Mr Carpenter had been a member for more than 40 years, also said goodbye to their "oldest Mackeral".

"Alf was a big personality at the Mackerels and loved his Sundays for over 40 years with the Mackerels. Alf loved to tell his stories or recite a poem," the social media post said.

"We will miss you Alf RIP."
