South Africa is one of the developing economies. Most of its provinces are in rural areas and have poor or lack of reliable critical infrastructure to enable development as in the case of urban areas. Infrastructure refers to physical structures that serve as the underlying foundation for the functioning of an economy. It includes physical facilities such as communication systems (telephone lines, broadband), and power supply systems (electrical grids, dams, etc.). The focus of the study is on information communication technological infrastructure (ICT) such as telephone and broadband networks and electricity infrastructure that support the adoption of e-learning. Many schools in South Africa are in rural areas and are attended by the majority of learners. These learners should perform the same way as learners in urban schools. Urban schools have better access to ICT infrastructure. Due to a lack of equitable ICT infrastructure, many education institutions back-tracked from the hybrid teaching mode implemented during the coronavirus (COVID-19) lockdown to the traditional class/lecture-room mode of teaching. It is revealed in the study that South Africa struggles in the area of infrastructure development. These affect the achievement of sustainable development goals (SDGs) which are heavily dependent on infrastructure, including education. E-learning offers a better advantage compared to traditional class/lecture-room-based education. ICT infrastructure that supports the provision of e-learning is not equitably distributed, and those that are available are not enough and reliable. South Africa is reported to need R4.8 trillion to achieve its critical infrastructure goals, indicating a dire need for infrastructure investment. Under-investment in infrastructure affects all sectors of the economy, including the education sector.
