He is the former Leader of the Official Opposition in the Eastern Cape Provincial Legislature, the former Provincial Leader of the Democratic Alliance (DA) in the Eastern Cape, a former Mayor of Nelson Mandela Bay, a former Member of the Mayoral Committee (MMC) for Human Settlements in the Nelson Mandela Bay Metropolitan Municipality, a former member of Parliament, and the DA's former Shadow Minister of Co-operative Governance and Traditional Affairs (COGTA).

[2] Bhanga joined the African National Congress and became the party's Nelson Mandela Bay Youth Leader, and SRC President of the Port Elizabeth Technikon where he obtained his first qualification in Public Administration.

[14] The DA did not win a majority on the Nelson Mandela Bay city council and lost nine seats.

[15] The DA's Federal Executive (FedEx) approved Bhanga's return to the provincial legislature on 29 November 2021 and he resigned as a councillor on 2 December 2021.

Bhanga said that his decision was influenced from the trauma he had suffered from after having been involved in a fatal car accident in August 2021 which left two people dead.
