Nahid, who has emerged as Bangladesh's pace spearhead in recent years, was ruled out of the two-match series with a Grade 2 side strain, ending hopes of seeing him bowl against the likes of Steve Smith and Marnus Labuschagne on Australian pitches.
The right-arm quick has taken 38 wickets in 12 Tests since making his debut against Sri Lanka in March 2024 and has earned global attention for his express pace.
Since his debut, Nahid has averaged 141.54 km/h, faster than Mitchell Starc's average speed over the same period, while his quickest delivery has been clocked at 151.96 km/h.
Salahuddin admitted he was among those excited to watch Nahid in Australian conditions but urged fans not to dwell on his absence.
"To be honest, I was also very excited to see Nahid bowling bouncers to Australian batters. That was something I was really looking forward to. Since it hasn't happened, there's no point regretting it. I believe the other bowlers, if they bowl smartly, can also do very well," Salahuddin told reporters.
Despite Nahid's absence, Bangladesh still have an experienced pace attack featuring Taskin Ahmed, Hasan Mahmud, Ebadot Hossain, Khaled Ahmed and uncapped Musfik Hasan for the historic tour.
Bangladesh will play a Test series in Australia for the first time since 2003, with the opening match scheduled to begin in Darwin on August 13.
Salahuddin remains optimistic about Bangladesh's red-ball side and believes the team is capable of making significant progress.
"I'm always optimistic about our Test team. The players who play Test cricket understand themselves well and know their goals. They are more organised than others. I don't see any reason why they can't perform well."
Looking beyond the Australia series, Salahuddin stressed the importance of Bangladesh's upcoming Test schedule.
"We have four away Tests, and I hope we can get some good results from them. Then we have four home Tests. If we win those four at home, I think we can move into the top two or three teams in the rankings."
