The 2018 AFF Championship qualification tournament was the qualification process for the 2018 AFF Championship, the twelfth edition of the AFF Championship. Brunei and Timor-Leste contested the tenth and final remaining berth for the AFF Championship final tournament in two home-and-away matches.[1] On 7 August 2018, organising committees confirmed the venue where Timor-Leste will play Brunei has been changed due to floodlighting issues. The opening match was held at Kuala Lumpur Stadium, Malaysia, not as per originally planned at National Stadium, Dili.[2]
Timor-Leste advanced to the AFF Championship group stage and were placed in Group B after winning by 3–2 on aggregate from two qualifying matches.[3] [4]
