The array of internet options available to the average Aussie is getting to the point of being overwhelming, especially if you're just after the cheapest plan going.

Thankfully, we've done the hard yards and sifted through all the fine-print to figure out which ones offer the most genuine value for your dollar.Whether it's NBN, ADSL or cable, there's a wide variety of pricing tiers available and they all come with quirks and caveats that you'll need to look out for.

Start up fees, lock-in contracts, compulsory modem purchases – we've done the maths to find you the best deal.Cheapest NBN plansTPG| 10GB data | NBN12 | 18-month contract | $29.99 pm (+ $30 upfront)If you're after a bare-minimum NBN connection then TPG's got the cheapest plan available, with an included modem and only $30 upfront it's the least you'll pay to get on the NBN.

The catch is that you'll only have 10GB/m to play with and it's an 18-month contract.Total minimum cost is $569.82 over 18 monthsExetel | 100GB data | NBN50 | No lock-in contract | $49.99 pm (BYO modem)Although it's not the absolute cheapest, Exetel is offering the best overall value on NBN speeds above the basic 12Mbps tier (i.e.

the same speed as basic ADSL).

Although you'll have to either provide your own modem or buy Exetel's for $79 delivered, this $49.99 plan is still a complete steal for an NBN50 connection with no lock-in contract or upfront fees.Total minimum cost is $49.99View DealCheapest ADSL plansDodo | 101GB data | ADSL2+ | 24-month contract | $20 pm (requires phone line)If you already have a phone line to run your ADSL over, then Dodo is offering the cheapest possible plan for the service right now, with 101GB of data and an included modem at only $20 per month over a 24-month contract.

No lock-in contract, unlimited data, and nothing to pay upfront (unless you want their modem for $79).

Frankly, there are cheaper plans, but we don't recommend signing up for them given how much they'll cost you with hidden fees and contracts.Total minimum cost is $54.99View DealCheapest cable plansOptus | Unlimited data | Cable | 24-month contract | $75 pmYou can pay marginally less for a Telstra cable plan, but it doesn't come with unlimited data and will set you back $99 upfront.

We recommend this 24-month Optus plan as the best value cable option overall, but you can opt for a month-to-month plan if you're willing to drop $200 upfront.Total minimum cost over 24 months is $1,800View Deal
