For the past ten years and more, South Africa has been beset with ‘loadshedding,’ the term used for the electricity blackouts that are now almost daily occurrences. The number of hours of loadshedding varies per day, and you can access an app from the main electricity provider to find out the loadshedding schedule for each day. Banks, shopping malls, hotels, petrol stations and other large businesses almost all have generators to enable them to continue their operations. The conference venue and University of Johannesburg have back-up facilities and we do not anticipate that conference delegates will be affected adversely by loadshedding during the conference events.

Plug type D is the main plug type in South Africa. It has three round pins in a triangular pattern. There are three other associated plug types that can be used in many places: types C, M and N. Plug type C is the plug which has two round pins, and plug types M and N both have three round pins. South Africa operates on a 230V supply voltage and 50Hz. Many modern hotels provide outlets for usb ports and EU sized plugs.

If you are staying with a friend or family, you are advised to contact their family doctor or dentist.


​Health Services

South Africa has some of the best hospital care on the African continent. However, most of this comes at a cost through private providers. There is low-cost treatment available through state hospitals in all provinces, charged at the standard 40% subsidized rate. Residents who cannot afford private healthcare mostly use this.

Private hospital care in South Africa is of a similar standard and price to many western countries. If you are covered for hospital treatment through a private insurance plan, you will need to check how much of the treatment costs you will have to pay for upfront and claim back through your insurance provider.

Around 79% of doctors in South Africa work privately. There are also around 200 private hospitals across the country. Two of the biggest private providers are Netcare and Mediclinic, which run many hospitals. Private services can be accessed through private health insurance in South Africa. You can choose your own coverage plan and will typically have to pay for services upfront and then claim for reimbursement.



A wide variety of painkillers, vitamins and cold treatments can be bought without prescription in any South African supermarkets, kiosks. To obtain medicines which have been prescribed by a doctor, you must visit a pharmacy (Chemist).



Water in South Africa is not always filtered, so it is best to ask if tap water is potable (it is often acceptable for coffee and tea after boiling). All hotels generously provide bottled water daily and the conference will provide filtered and/or bottled water.



Joburg has numerous places where you can use a computer with internet access, including almost any hotel. Nowadays many shopping malls, restaurants, coffee shops and cafes also offer free Wi-Fi services.


Time zone

South Africa uses South African Standard Time (SAST) which is UTC+3. 



The amount you tip in South Africa will depend on where you are and what type of services you’re buying. As a rule, expect to tip around 10% of the bill. If you get exceptionally good service, you may say thank you with a tip closer to 15-20%.


Weights & Measures

By 1974, South Africa converted to the metric system and therefore uses meters as its measurement for length, litres for liquids and kilos for weight. This is different from countries that use the Imperial System. The conversions between these two systems are:

Kilometers & miles
1 mile = 1.609 kilometers
1 kilometer = 0.621 miles

Liters & gallons
1 gallon = 4.546 liters
1 liter = 0.220 gallons

Kilos & pounds 
1 pound = 0.453 kilos
1 kilo = 2.204 pounds
