Great Britain has been drawn in Group A, which also contains Bosnia-Herzegovina and Iceland. Achara told gbbasketball.com, from his base in Bulgaria, that GB would face a tricky assignment. "When you're playing in Europe and you're playing to qualify, there is no such thing as an easy group," he said. "But I'm very comfortable with the group."
British fans have reacted positively via social media to the draw. There appears to be a real belief among supporters that GB can reach their fourth successive EuroBasket Finals, which Achara is quick to acknowledge.
"It's great to get the expectations and it's going to be a learning process to develop that mindset as a team. We've always been underdogs - it's just the way it is. To go into games, you have to believe you are the best and make sure that you prove it. As an underdog team, we were always hungry to go and beat teams who were deemed better than us. I'm sure Bosnia and Iceland are thinking exactly the same thing and I really believe that especially away from home, this will be a very difficult challenge. "
Britain have met the Bosnians in two of their three successful EuroBasket qualifying campaigns. Chris Finch's side met up on three occasions in 2008, starting with a 100-98 win in a tournament in Turkey. Great Britain won 82-74 when the nations met in the qualifiers on September 10th 2008 at Birmingham's National Indoor Arena. But it was the Bosnians who came out on top in Cazin ten days later (80-89) although, by that stage, Great Britain had already qualified for the 2009 EuroBasket Finals.
The two sides met again two years later and GB claimed home and away wins in August 2010, winning by four points in Sarajevo (84-80) with Dan Clark scoring a game-high 23 points with five out of five from the 3-point range. Nate Reinking was next highest with 21, while Luol Deng and Pops Mensah-Bonsu added 16 each.
Great Britain prevailed again at Liverpool's Echo Arena (94-85) to seal an appearance in Lithuania's 2011 EuroBasket Finals with Deng producing his GB record-scoring performance with 38 points while Mensah-Bonsu also contributed 32 to the final scoreline.
Achara was part of the GB squad that night and the experience makes the Scot a wary man.
"That game in 2011 was such a tough game. If I remember rightly, we were quite fortunate. Pops really carried us through in the last few minutes to seal the deal. They have such talented players and I don't know who's going to be available to them. Bosnia is a very experienced basketball nation so it's one of those situations where we know we have what it takes to beat them, but it won't be a walk in the park for us."
Bosnia-Herzegovina's stand-out name is 29 year-old forward Mirza Teletovic who is in his second NBA season with Brooklyn Nets. But Great Britain may have an inside scoop on how he is playing right now, with GB Head Coach Joe Prunty also lead assistant coach at the Nets.
"Teletovic is a very talented player. He can really help any team and those types of guys tend to take care of business," added Achara.
Great Britain has never played Iceland in EuroBasket qualifiers and the last time the two sides faced each other was in 1976. GB were successful in both games played on Icelandic soil - winning 82-76 and 81-74 - with current British Basketball Federation Chairman Bill McInnes captaining the side.
Achara has some insight into how Iceland's modern version will shape up. "Iceland is a little bit more unfamiliar. They're a smaller team, but they shoot a lot of three's. So if they're hitting shots, they can be very hard to stop. I've got a good friend who plays for them so I know they'll definitely be up for the challenge. "
