The best Australian iPhone 6S Plus plans

Telstra

If you need a lot of space but a small amount of data and want to use Telstra's 4GX network, then the smallest amount of cash you'll be paying is $112 a month. For that, you get 1GB of data, $550 worth of talk and text and the handset, of course.

If you're willing to spend $118 a month, then you can get the 128GB handset with 2.5GB per month and $1,000 worth of talk and text.

If decent data is a prerequisite, you'll need to spend at least $135 a month. That will get you 7GB of data (6GB plus a bonus gig) and unlimited talk and text.

And for the heaviest users, Telstra offers 15GB (10GB plus 5GB bonus) with unlimited talk and text on a $165 a month plan.

Optus

The Optus plans for a 128GB iPhone 6S Plus start at $91 a month. You'll get a fairly restrictive 500MB of data every month, but unlimited talk and text in Australia.

Upping your repayment up to $100 a month will give you a full 3GB of data and up to 150 minutes of International calls in addition to the unlimited national talk and text.

At $107 a month, you'll get 6GB of data, unlimited talk and text and up to 300 minutes of international calls. But an extra $15 a month on top of that will double the data to 12GB (10GB plus 2GB bonus data) and 400 minutes of international talk time.

The top of the line Optus plan for the 128GB iPhone 6S Plus comes in at $149 a month, and gives users 20GB of data (16GB plus 4GB bonus), unlimited talk and text, 500 minutes of International calls and the bonus of up to 10 days of Optus travel Packs.

Vodafone

The entry level plan for Vodafone customers wanting the largest capacity of iPhone 6S will set you back $98 a month, a plan that incorporates 1GB of data (500MB plus 500MB bonus), along with unlimited talk and text and access to Vodafone's $5 roaming offer.

Of course, with a phone that big, most people will need a larger data plan. The next step up delivers 3GB of data each month, unlimited talk and text and $5 roaming, plus 120 standard international minutes to selected countries. All for $109 a month.

8GB of data (6GB plus 2GB bonus) is included in the $110 per month plan, which improves the international call offering to unlimited for calls to 10 selected countries, plus 120 minutes to others. It also includes the unlimited talk and text in Australia and $5 roaming deal.

The next two plans are identical to the $110 a month plan, except with bigger and bigger data offerings. For $121 a month you'll get 12GB of data to use (10GB plus 2GB bonus), while $140 a month will deliver a massive 20GB of data (15GB plus a bonus 5GB).

Virgin Mobile

It's actually quite amazing that you can grab a 128GB version of the iPhone 6S Plus for $79 a month. Admittedly you only get 300MB of data and $300 worth of talk and text, but still, it's a decent way to get the top of the line Apple smartphone.

Of course, if you want to actually use the device, you'll need to pay up at least $91 a month, which delivers $450 worth of value and 1GB of data.

An extra buck (or $92 a month) will double that data to 2GB, as well as boosting the talk and text value to $500. But start paying $100 a month and you'll get unlimited talk and text plus 4GB of data each month.

The next three plans all offer unlimited talk and text, but with varying quantities of data. At $102 a month you'll get 6GB of data to use every month, $105 a month delivers 9GB and $112 a month gives 13GB of data to use.
