The top under-14 and under-16 players from 12 Southern African countries have registered for the tournament, with 75 boys and 63 girls having arrived in Windhoek over the weekend.
Each nation is entitled to send a team comprising a maximum of 12 players and one coach for those nations with up to six players, or two coaches for those nations with seven players or more.
As the host nation, Namibia was allowed to enter more players for the tournament and the players have prepared thoroughly at an intensive three-day tennis clinic organized by the NTA.
The top seven players in singles in the under-14 and under-16 categories at the Southern African Junior Championships in Windhoek will qualify to play in the main event of the African Junior Championships, which will take place in March and April 2017. In addition, in each of these age groups, one wildcard selected by the ITF and CAT and will be offered to a player from the region.
Samson Kaulinge, chairman of the NTA said: "Namibia is proud to host this important junior tournament for the first time. We will do our best to make it a success.”
Kallie Heese, tournament director said: "The organisation of an international tournament of this magnitude is not possible without the support and engagement of many volunteers. I am grateful to have such a dedicated team of coaches and a number of parents who have done their outmost to help with the preparation of the courts and the accommodation of the players.
"We have to thank Coca Cola Namibia, which came on board as a sponsor at short notice. We are also grateful for the support of the Namibian Ministry of Home Affairs, which went out of their way to facilitate the issuance of visas for players and their international coaches.”
