The short answer: our code ADAMANDLINDS works from Australia exactly the way it works everywhere else. It takes 5% off any Holafly destination eSIM and 10% off the monthly Plans. There is no separate Australian code, no AU-only voucher, and no secret 30% code hiding on a coupon aggregator site. This page covers what the code applies to and how the numbers stack up against Telstra and Optus roaming in actual dollars. Bali gets its own section further down.
Holafly eSIM
Works on every destination eSIM, including Indonesia, Japan, Thailand and Europe.
Use code ADAMANDLINDS for 5% off destination eSIMs or 10% off Plans.
Get your eSIMWhat the code covers
Holafly sells two things. Destination eSIMs are the classic product: pick a country, pick a number of days, pay once, get unlimited data for the trip. The code takes 5% off those. Plans are the newer monthly subscription, one eSIM covering 160+ destinations, and the code takes 10% off those instead. If you go for an annual Plan, the 10% stacks on top of the built-in annual discount of around 22%, which lands the total near 30% off the monthly rate.
We have used Holafly across four years of full-time travel with three kids, from Japan to Finland to a Shanghai trip where the built-in VPN on the China eSIM did the work our banking apps needed. Everything we publish about the company, including current deals, lives on our Holafly page.
The maths against Australian roaming
This is the part that matters more than the discount. Telstra's International Day Pass charges $10 AUD per day in Zone 2, which covers Japan, Indonesia, Thailand, Vietnam, the US and most of Europe, and caps you at 2GB of data per day before charging another $10 for a top-up. Zone 1, which is basically New Zealand and the Pacific, runs $5 per day. Optus charges $5 a day for 5GB on postpaid plans, and Vodafone charges $5 a day to use your normal plan inclusions overseas. Every one of those charges is per phone, per day. Two adults on a two-week Japan trip with Telstra pay $280 in roaming before anyone opens Google Maps.
A Holafly destination eSIM is one upfront payment for the whole trip with unlimited data, and the code takes 5% off that number at checkout. Here is the comparison for a common trip length.
| Option | Daily cost | Data | 14 days in Japan |
|---|---|---|---|
| Telstra Day Pass | $10 AUD/day | 2GB/day cap | $140 per phone |
| Optus roaming | $5 AUD/day | 5GB/day | $70 per phone |
| Vodafone $5 Roaming | $5 AUD/day | Your plan's data | $70 per phone |
| Holafly Japan eSIM | One payment | Unlimited | One price, minus 5% |
We put a full country-by-country breakdown, including AUD, in our international price comparison if you want to see how Holafly's pricing shifts by market.
Telstra's Day Pass activates the moment your phone uses any data or sends so much as a text on an overseas network, and the charge applies for the whole day even if you switch roaming off five minutes later. If you plan to run a Holafly eSIM, turn off data roaming on your Telstra line before the plane lands.
The routes Australians actually fly
Bali first. Holafly's Indonesia eSIM covers Bali along with the rest of the country, comes with unlimited data, and the 5% code applies. Bali sits in Telstra's Zone 2, so the Day Pass alternative is the same $10 a day it costs in Paris.
Japan is the route we can speak to personally. We have spent 325 days there across 13 trips, most recently flying into Osaka from Da Nang in May, and a Holafly Japan eSIM has handled train timetables and five people's worth of hotspot requests on every one of them. Thailand and Vietnam are the same story: 327 days in Thailand and over 200 in Da Nang alone, all on Holafly data. For a multi-country trip through Italy and France, the Europe regional eSIM covers 40+ countries on one purchase, so you cross from France into Switzerland without touching your phone settings.
We keep a running review of the service, including the things we do not love about it, in our Holafly review. The video version is here.
Longer trips: Plans and the 10% code
If your trip runs past a month, the monthly Plans usually beat buying destination eSIMs back to back. One eSIM covers 160+ destinations, the fee is fixed each month, and hotspot is included on both tiers. This is what we run as a family and it is where the code does its best work, since 10% comes off every billing cycle rather than a single purchase.

Get Unlimited PlanPrices are listed in USD; the checkout converts for Australian cards, and if you want to see figures before you buy, the site has a currency selector. One more Plans detail worth knowing: if you cancel, Always On keeps giving you 1GB per month in 70+ countries at no charge, so the eSIM stays useful for a Bali long weekend six months after your big trip ends.
Keeping your Australian number
Holafly is data only, and that turns out to be the right design. You keep your Australian SIM active in the second slot with data roaming switched off, and it keeps receiving the SMS codes your bank and myGov insist on. Receiving a text does not trigger Telstra's Day Pass charge, so your number stays alive for free while the eSIM carries all the actual data. We wrote up the details in do you keep your phone number with Holafly.
Install the eSIM at home on your own Wi-Fi before you fly. Activation takes about two minutes, and Kingsford Smith departure-lounge Wi-Fi is not where you want to be scanning QR codes.

FAQ
Holafly discount code questions from Australia
The 10% applies to Holafly Plans, the monthly subscription, with code ADAMANDLINDS. Destination eSIMs get 5%. The same code works in both cases and there is no Australia-specific version.
Yes. The Indonesia eSIM covers Bali with unlimited data options, and the 5% code applies at checkout.
Holafly lists prices in USD or EUR by default, with a currency selector on the site. Your card is charged in whichever currency you check out in, so an Australian card converts at your bank's rate unless you switch the display to AUD first.
Same thing, different countries. Holafly's checkout calls it a discount code, and ADAMANDLINDS goes in that field regardless of what you searched for to get here.
Not as a straight code. Coupon sites advertising 30% off are recycling expired or fake codes, which we covered in our post on why 30% Holafly codes do not exist. The closest real equivalent is an annual Plan, where the built-in annual discount plus the 10% code lands near 30% total.
