The leg-spinner was celebrating her team's victory over Renegades when her boyfriend, Tayler McKechnie, entered the field and went down on his knees to propose to her, a video of which was shared on social media by Adelaide Strikers.
The 22-year-old Amanda was seen saying "yes" as her teammates egged the couple on in the background.
"When I saw him on the field, I just thought, 'get off, we're trying to take a team photo'. I had no idea what was really happening, but I'm so happy... I'm still shaking," Amanda was quoted as saying by The Advertiser.
Amanda made her debut for Australia in 2016 and has played 8 T20Is, 12 ODIs and 1 Test for the national team.
