THE month of August will always be remembered as one packed with milestones and achievements for the Wallace family.
Pelican Waters Swim Club's Tessa Wallace headed for Europe for final chance training on Saturday at Calella, Barcelona before her chance for gold at the London Olympics in the 200m breast stroke.
Tessa, 18 left behind a cavalcade of supporters who will cheer on their home-grown Olympian when she takes to the pool for her first heat on August 1.
But there is one special little fan that Wallace will be itching to come home to meet.
Tessa's older sister Kristy Perkins is heavily pregnant and due to give birth on the same day as the women's 200m breast stroke final.
"It's so crazy to think I'm due the same day Tessa swims," Kristy, 26 said.
"If I haven't given birth by August 3 when the finals are televised, I will have to make sure I am really calm when I'm watching Tessa swim.
"Mum was really torn - should she be there for their daughter's first Olympics or her other daughter's first baby, but Mum and Dad have done the right thing and they will be back the day after the finals anyway.
"It will be such a miracle if the baby is born and Tessa swims in the finals."
The Caloundra Weekly caught up with Tessa at the Caloundra Aquatic Centre on Thursday night as she wrapped up one of her final training sessions.
Tessa was farewelled by dozens of family and friends at the club as they cut a cake in celebration.
"Calella will be my last week of full training before the Olympics," Tessa said.
"I'll be training with a few squads with swimmers like Jess Schipper, Libby Trickett and Eamon Sullivan.
Tessa said she can't wait to come home after the closing ceremony to see her niece or nephew.
"I'll be sad to not be there for the birth, but I'm also excited at the same time. When I get back I'll have a baby to give hugs to and I'll be an aunty," Tessa said.
