Luke Neville.

current or former?
Sammy Harris (7'3) i think it the tallest by a inch over Neville (7'2)

current Pledger (7'0) & Schenscher (7'1) are the biggest

Nevill is an NBL player again, just signed with Townsville.

So it's Nevill>Schensch>Pledger

Pledger and Schenscher are both listed between 213 and 216 in various places. I think they are both around that 215-216 mark though.

Where did Sam Harris end up? Is he still playing anywhere?

This list is according to the NBL website, placed in order of height. Nevill isn't listed as yet but I've included him since he's signed with Townsville:

Luke Nevill - 218cm (7'2), 120kg
Luke Schenscher - 216cm (7'1), 120kg
Alex Pledger - 213cm (7'0), 113kg
Daniel Johnson - 212cm (6'11), 108kg
Ben Allen - 211cm (6'11), 113kg
Matt Burston - 211cm (6'11), 103kg
Ian Crosswhite - 210cm (6'11), 115kg
Pero Vasiljevic - 209cm (6'10), 115kg
Cameron Tragardh - 209cm (6'10), 106kg
Russell Hinder - 208cm (6'10), 110kg
Seth Scott - 208cm (6'10), 109kg

That is every current (or incoming) NBL player who is 6'10 or taller. I have left out development players Lachlan Winter (Tigers) who is 211cm (6'11) and Matthew Andronicos (Taipans) who is 208cm (6'10) simply because they're not likely to see much, if any, game time this year.

The Wildcats and Hawks are the only teams in the league without a player who is 6'10 or taller. Their tallest players are Jeremiah Trueman and Larry Davidson respectively and they are both 206cm (6'9).

Have to admit I've only ever seen Nevill listed at 218cm (7'2), be it on the NBL or Indiana Pacers site.

And I have to make a correction on Alex Pledger. The NBL site actually lists him at 215cm (7'1), not 213cm (7'0).

Harris hasn't played in the league for a couple of years..

I read 'heaviest' and my mind instantly turned to Pero Cameron. I know he isn't a current player but surely one of the heaviest in history

Dean Uthoff would surely make the list...

Helliwell - '120kgs '- one foot on the scales ,I'd say,one big unit . 211cms.

Tallest all time.

Sam Harris? followed by Andy Campbell.

Heaviest all time is an interesting one.

Maybe Utoff.

Norman Taylors arse probably weighed 80kg on its own.

Ontario Lett - was trying to remember his name!

Jim Havrilla (spelling) back in the 90's ... broke a back board in the pre season 3-3 tornament on the Gold Coast

Acie Earl? He was a big unit.

Sammy Harris is playing SEABL for north west (off the bench), the NBL did list him as 7'4 for some strange reason. but his only 7'3
the Earl weight bloomed out here with kings staff worried about it.
there were reports of him getting up to 160kg. I don't think there was anyone as big of a unit than that

i think the question needs to be asked former or current.

Out of curiosity, does anyone know how tall Willie Simmons is? I read one news article where it claimed he was 210cm (6'11), yet from what I've heard and read elsewhere he was a legitimate 7 footer at around 213 or 214cm.

As for the heaviest.....I know he wouldn't have been the heaviest in the league but he would have been close to the heaviest for his height...how heavy was Chris Blakemore?

Todd Mundt who use to play for the Newcastle Falcons was tall timber as well. I seem to remember he was listed as 7"1 or though on Wikipedia he was listed as 7 feet and weighs 250 pounds.

Hodge, his ego was huuuuuggee

Chuck Kornegay- was not tallest at 6"9 but he was certainly one of the heaviest at 235 pounds. The guy was a big drink of water, in my opinon I thought Kornagay was unlucky not to be given a chance in the NBA.

David Van Dyke- was also a big beast at 6'10 and 240 pounds.

Matt Zauner was a pretty big unit as well... sure moved like one...

Pero Cameron was around 130kg! That's not too far off 300. He is just huge all over, as unmovable in the post as Shaq.
