How major electricity suppliers take advantage of rural and regional customers

This is what NSW Dept of Industry, Resources and Energy advises owners of roof top solar power previously covered by pre 31 December 2016 feed-in tariffs:

It is up to individual customers to decide what metering arrangement will best suit their property, system and budget. You may wish to refer to the fact sheet Small Scale Solar PV Generators.

Generally if you do not receive a feed-in tariff, or if your feed-in tariff is lower than the price you pay for electricity, you are likely to be better off with a net meter. Under net metering, electricity from a solar PV system is first used to meet any consumption that takes place at the time of the generation. This means that for each kilowatt hour you consume of your own generation, you save the retail price that would otherwise be paid for that consumption.

Customers are encouraged to contact their distributor or accredited service provider to discuss their metering options before making a final decision.

The writer of this letter to the editor, published in the Clarence Valley Independent on  22 February 2017, appears to be currently exporting all his solar power to a residential energy supplier for a pitiful return.

This is occurring because the power supplier (which based on stated costing is likely to be Origin/Essential Energy) is refusing to install a net meter function for the solar power system because of alleged deficiencies in mobile coverage.

Mobile cover is required as the digital net meter in question is to be read remotely and, apparently existing NBN satellite or fixed wireless cover in the Braunstone area is not considered satisfactory by the energy company's representative.

I'm sure there are more than a few Northern Rivers residents in the same situation as Mr. Philipse and, I rather suspect that residential energy suppliers are quite content to have it continue that way. As the est. $18 cents per kwh hour net profit earned from a customer's rooftop solar power output by charging top price of 24.2 cents per kwh for that same solar power as residential supply back to that customer, is money for jam for these companies.
