The return of the mercurial trio of Luongo, Robbie Kruse and Tom Rogic, after varying lengths of absence, gives the Socceroos coach a dizzying concoction of possibilities to ponder ahead of the qualifiers at Perth's nib Stadium on 3 September and in Tajikistan five days later.
Already building up a nice head of steam, after two assists in consecutive wins for his new club Queens Park Rangers in the Championship, Luongo can't wait to be unleashed alongside a resurrected Rogic and a recalibrated Kruse.
All three didn't play in June as the Socceroos opened their qualifying campaign with a narrow 2-1 win in Kyrgyzstan, with their flair and artistry sorely missed.
Australia's 2015 AFC Asian Cup hero, Luongo is enthralled by the attacking vertuosity at Postecoglou's disposal.
“It’s exciting when you look at the squad and the amount of threat we carry in attack," Luongo said.
“There’s a lot of creativity and talent in the final third when you look at the attacking midfielders and wide players we have.
“Whoever the coach goes with, there are goals in the squad for sure - when you have players like Robbie Kruse and Tom Rogic available again, and with Mathew Leckie and Tommy Oar also a huge part of things, and of course Tim Cahill doing his stuff."
“It’s a matter of who the boss wants to go with but whoever he chooses, we can hurt teams."
Rogic, who is back firing for Celtic after being dogged by long-standing groin problems, last featured for Australia 16 months ago in a 4-3 loss to Ecuador in London.
While Kruse was injured in the Asian Cup final but is steadily receiving game time off the bench for Bayer Leverkusen, after returning from a ruptured Achilles.
"Against Bangladesh, I think it will be enjoyable to play when you have that sort of line up because you are going to see a lot of chances created, and hopefully plenty of goals too," Luongo said.
"Our seasons are all up running now and we have that fitness and sharpness which is what you need going into these games. I am really looking forward to them… you never pass up the chance to play for your country.
"I have missed a couple of big games, which was shame after the Asian Cup because I just wanted to keep going.
"But it didn't happen and hopefully I will get back to that against Bangladesh."
Luongo, who has started in all four of Rangers' opening league games as it looks for a quick return to the Premier League, is expected to be rested for Wednesday morning's (AEST) League Cup tie, with the weekend clash against Jason Davidson’s Huddersfield Town in mind.
"We got off to rocky start losing at Charlton and we then went two-up against Cardiff but allowed them to nick a late equaliser, but coming back from two down against Wolves has set us up a bit," said Luongo.
"A lot of people may have been a bit worried about our squad this year, but when we are good we are really good."
"There's still a lot of room for improvement but the amount of chances we are creating is really positive."
With that in mind, Luongo is hoping that as the transfer deadline draws near, England striker Charlie Austin will remain at the club amid intense interest from West Ham and Crystal Palace.
After playing in a deeper role for the opening two games, Luongo has become the designated No.10 for Rangers, and the chemistry with Austin, who has four goals already, has been instantaneous.
"He’s been scoring goals and his form is excellent. When you link up with players like that, it’s a great thing," Luongo said.
"We have developed a little partnership which we both like and it's been working for the past couple of games.
"I would personally love him to stay because he makes my job a lot easier. The first game of the season I was playing in a holding role… that’s where I thought my position would be, although with the Socceroos I have had more of free role.
"The manager has put me as a No. 10 for the past two weeks, and it’s paid off as I have loads of energy and that’s what we need in the side.
"I think I am doing a pretty good job for the team, and as a bonus, I can start getting involved in more goals, rather than playing as a holder and starting the play off, being secure and tight at the back.”
Equally adept in both roles, Luongo, 22, isn't yet sure which one will best suit his evolution.
"I don’t know what my best position is yet but I am just enjoying what I am doing at the moment,” Luongo said.
