The victory is not only the biggest ever in the COSAFA Women’s Championship, beating the 15-0 victory for Zimbabwe over Lesotho in 2002, but is also South Africa’s largest ever win in their history.
Despite resting a host of key players and without their numerous overseas-based stars, Banyana Banyana had too much quality for the islanders, who were on debut in the competition.
Captain Refiloe Jane, who netted twice in the final last year, scored four goals to showcase her quality, while there was also a hat-trick for Amanda Mthandi.
Hilda Magaia and Bambanani Mbane scored braces, and the other goals came from Tiisetso Makhubela, Ode Fulutudilu, Mamello Makhabane, Busiswe Ndimeni, Kholosa Biyana and an unfortunate own goal from Comoros defender Hanifa Melanie.
It was 6-0 at the break.
Head coach Desiree Ellis made changes at the start of the second stanza – bringing on Hilda Magaia and a debut appearance for U20 international Noxolo Cesane – and South Africa continued from where they left off.
She also brought on Ongeziwe Ndlangisa to earn her first cap for Banyana Banyana, coming in for Makhabane.
South Africa might not know quite what to read into this result with Malawi and Madagascar to come in their group, but it is certainly a statement on intent from the side.
Rudo Neshamba celebrated her return to the Zimbabwe national team for the first time since 2016 with a hattrick as Zimbabwe defeated Angola 4-1 to make the perfect start to their Group C campaign.
Neshamba played the poacher role superbly as she was given too much time and space in the Angola box and supplied some neat finishes to punish her opponents.
The Mighty Warriors had taken the lead through Emmaculate Msipa inside three minutes and by halftime led 3-1, with Neshamba adding a fourth in the second period.
Angola are competing at the tournament for the first time since they made the final on home soil in 2008 and scored a consolation through Cristina Makua.
Malawi and Madagascar appeared to be heading for a stalemate in their Group A clash before the She-Flames snatched victory late on with two goals in the final 10 minutes.
Experienced Salome Vinkhumbu scored the opener on 81 minutes and the points were made safe with two minutes to go when Zainabu Kapanda grabbed a second.
It was a deserved victory for the Malawians, who missed a host of chances in the game.
The action continues at the Wolfson Stadium on Thursday (1 August) when Mozambique and Eswatini clash in their Group C encounter (10h00 local time; 08h00 GMT).
Both sides know a victory is needed to stay in touch with Zimbabwe as only the top team in each pool and the best-placed runner-up advance to the semifinals.
That will be followed by two matches in Group B, the first seeing Zambia take on Mauritius (12h45 local; 10h45 GMT).
Zambia have yet to make a COSAFA Women’s Championship final and will be hopeful changing that this year after their showing at the African Women’s Championship in Ghana last year.
The final game of the day sees Namibia tackle Botswana (15h30 local; 13h30 GMT) in what should be a closely-contested encounter.
