Dew has not spoken publicly since his abrupt axing last Tuesday, after five-and-a-half seasons at the helm of the Suns.
Instead, the former premiership player with Hawthorn and Port Adelaide booked an impromptu holiday to the United Kingdom.
A friend of fellow South Australian Head, Dew was spotted in full Australia kit at training ahead of Wednesday's Test in Manchester.
He inspected the Old Trafford wicket and was spotted in deep discussion with Port Adelaide ambassador Head, fellow South Australian Alex Carey and Victorian quick Scott Boland.
His appearance in Australia's Ashes camp follows that of retired Geelong captain Joel Selwood, who shares a connection with the national team's coach Andrew McDonald.
The Suns board met last Monday night to vote Dew out despite the coach winning a two-year contract extension last season.
"It's good Stuey could get on a holiday over here," captain Pat Cummins said.
"He knows a few of the boys quite well, so it's good to have him around.
"We have some footy nuffs in our teams, so I am sure they will be picking his brain for their fantasy sides and we've had about 10 Geelong footy members come in with Ronny (McDonald), so it's good to have someone else."
