Ranked 27th in the world, the Angolans will be the only African representatives in the Women's competition and could potentially face GB in London in the latter stages of the competition.
This will be followed by a mammoth clash on Saturday evening as Great Britain take on Australia at the Motorpoint Arena.
The Opals are ranked number two in the world and will also be GB's first opponents in London when the Olympics get under way later this month.
GB's Natalie Stafford is looking forward to going up against the Australians: "I can't wait, they've lost a key player in Penny Taylor, they are beatable, and we're going to give it our best shot.
"I think we're going to give Australia a run for their money and they will be shocked at how physical and aggressive we are."
GB Coach Tom Maher, who coached Australia to a silver medal at the 2000 Sydney Olympics, is looking forward to taking on his former team: "They've got 12 great players for a start. Lauren Jackson's still a world superstar but they lost Penny Taylor, which is a blow for them."
Despite Taylor's absence, Maher expects Australia to send a message ahead of the meeting in London: "They are going to try and crush us but we want to get respect and play the best game we can against them."
On Sunday, GB return to Ponds Forge for the final game of the weekend as they take on France.
Like Australia, the French will also be in GB's Olympic group and booked their spot earlier this month at the Olympic Qualifying tournament in Turkey.
GB forward Julie Page, who spent two seasons playing in France, is looking forward to going up against a side ranked eighth in the world: "France is definitely a game I'm looking forward to. I've played against a lot of the French national team."
In addition to the GB games, Angola, Australia and France will compete against each other in the round robin format, while GB Men are also in action as they take on Portugal on both Saturday and Sunday.
