My name is Drew and I am a wildlife carer in Lake Macquarie, Australia. I have made this website for all the wildlife carers out there to help manage your animals in care and streamline reporting without the cumbersome spreadsheets!
If you are new to wildlife rescuing and want to understand what the data reporting is all about, start with the introduction section (click here)

The NSW Government regulates wildlife rehabilitation in NSW. As part of your obligations as be a wildlife rescuer/rehabilitator you undertake to report data on wildlife you interact with. This data ultimately guides government policy, scientific research and wildlife funding
A carer/rescuer does not directly report to the Government, your rehabilitation organisation (for example mine is Hunter Wildlife Rescue) will gather the data from all it's members and do a single bulk report every financial year. So your organisation sets your reporting requirements to them, typically this is more frequently (i.e. once a month) so as to avoid an overwhelming amount of work for the data coordinator all at one time.
The relevant Govt depeartment releases an official spreadsheet every year, this is the same spreadsheet your organisation will provide you to fill out for your wildlife. Click these links to see information directly on the Dept. of Environment website
So every month (or timeframe requested by your rehabilitation organisation), you fill in that spreadsheet and send it off to your data coordinator email address.
So why this website?? Well many people find spreadsheets difficult, especially with mobile devices, and the spreadsheet is missing many features a wildlife rescuer/carer would reasonably want - such as a mobile friendly interface, access from different devices, GPS locations, progress notes, ability to transfer animals among other things. So I have created this website to fill this need.
So this website provides a (hopefully) better experience in the day to day recording of your wildlife, and at the end of every month allows you to simply press a button to download the official spreadsheet already filled in with your animals, which you then send off to your data coordinator!
So as you can see, you are still completing your reporting obligations as the Government requires, but using a much friendlier system to do so. As a carer myself, I have no doubt you will find this easier. Having said that, if you love spreadsheets and you dont need any of the features on this website, you simply do not need to use it! This is an adjunct made with love by wildlife carers, not official and not a replacement.

You are greeted with the homepage whenever you aren't logged in. Either login or signup. For signing up see "Signing Up/ Updating Details Heading".
Mobile users can add a shortcut to their home screen for easy access. See instructions for apple here or android here
To get a feel for the website and learn how it works before you sign up, you may use the login sandbox@test.com with password password.
This login will reset every night and all associated data deleted, so be sure to sign up yourself before recording actual animal information!

Membership is always free. A couple of things to note:

The dashboard shows you all animals you currently have in care, and has a button to create new animals. There is also a search box (top right) to filter visible animals. Click each animal to view and update their specific details.
You will also see a menu button at the top right to access other functionality described below.
To remove an animal from your dashboard you can archive it (see "Creating and Editing Wildlife" heading).
This page shows information on a single animal. Make sure you press save when you are finished!
While plenty of the fields here align with NPWS reporting, there are many other new useful tools for carers. These include:

Simple page to create date-recorded progress notes. For example where you want to track progressive information such as animal weight, multiple vet appointments, enclousure movements etc. This is all entirely optional to use, and is not reflected in the NPWS Fauna Data.

You still need to export the spreadsheet and send to your fauna data coordinator every month
The main purpose of this page is to download your animals in the format of the official NPWS Fauna Data Spreadsheet which you will then provide to the data coordinator monthly. Choose a date range and press "Download".
All animals that have either a encounter date or a fate date within those periods will be downloaded. This is to allow for animals spanning multiple data reporting periods.

This history page shows a table of all animals currently and previously in your care. You can access archived animals from here too. The table is interactive, click the columns to sort, enter keywords in the search box to search, and click the drop down menu box to hide and show other animal data columns.
