Software Development Review from Grzegorz Grabczak
We worked with Zealous System on an AI-powered fraud triage solution for one of our clients in the Europe financial services sector. The project involved a complex fraud investigation workflow where analysts were handling a large number of alerts and gathering information from multiple systems. Zealous System worked closely with us to understand the requirements, existing processes and expectations of the end client before moving into development. The team developed an AI-powered fraud triage agent that brings relevant information together, helps prioritise alerts and provides explainable recommendations while keeping human analysts involved in important decisions. What I appreciated was the team's ability to understand both the business and technical sides of the project. Communication was consistent, and they were responsive when requirements evolved during development and testing. The solution helped streamline the investigation process and reduce the amount of repetitive manual work involved in reviewing fraud alerts. Overall, we had a positive experience working with Zealous System. They were a reliable technology partner for us on this project, particularly given the complexity of introducing AI into a financial services environment.
DIPAK VAIDH's Review Sourced from Google
I visited Zealous System on 16th June 2025 for the walk-in interview announced on LinkedIn for interns/freshers in Python, PHP, WordPress, .Net, and QA roles. Despite clearly stating it was open for freshers, upon arrival, all Python candidates, including myself and my sister, were told they only accept those with prior experience, as interns are directly placed on live projects. This information was never mentioned in the post. The company blamed the marketing team for the misleading post. This experience wasted our valuable time, energy, and travel expenses. I urge the company to coordinate better internally and post accurate job/internship information to avoid misguiding freshers who genuinely seek opportunities.
Ravi Prajapati's Review Sourced from Google
Zealous System is outstanding when it comes to AI development! Their team helped us build a smart, AI-powered software solution that completely transformed how we manage data and customer interactions. They explained complex AI concepts in simple terms and delivered a solution that works flawlessly. From planning to post-launch support, everything was smooth and professional. Highly recommended if you're looking for reliable AI experts!

Linda Jane's Review Sourced from Google
Our startup idea is quite complex because it solves some of the most challenging problems in the fintech industry. This idea requires a product that not only leverages the power of Al (LLM) but also incorporates cutting-edge technologies like RAG (Retrieval-Augmented Generation). It was very challenging to find a team with firsthand experience in all these advanced technologies, but we found Sunrise Technologies. They are one of the few companies in Australia capable of solving the most complex tech problems.
Wil Emmett's Review Sourced from Google
I'm currently working with Sunrise Technologies to build a mobile application with an integrated AI agent. Before choosing Sunrise, I spoke to many mobile app companies in Sydney, and I can confidently say my decision has been well rewarded. The journey so far has been excellent and Sam and the team have gone above and beyond to meet my needs. I’m happy to recommend them to anyone looking to build software products. 5 stars from me

Tyler was amazing throughout the process of designing my website. He was prompt with always getting back to me and extremely accommodating to my changes. Not only did he help me navigating the set up of a website for the first time but he also arranged my email account, google business and the SEO for the website. He made a stressful process very seamless and I can't recommend him highly enough. Very skilled and helpful but extremely efficient at getting the work done.

Tyler was absolutely awesome to deal with. He was prompt with his responses, was incredibly helpful and helped us so much with preparing our website design.

Thanks again so much Tyler.

We used Apex Designs to create a website for our earthmoving business and we are over the moon to say the least. Tyler was professional, punctual and very knowledgeable.

Top custom software development companies in Australia can help businesses create tailored web and mobile applications to automate operations, improve efficiency, and stand out in their target markets.
More specifically, these companies can deliver:
To further highlight the benefits Australia software development firms can deliver, our researchers have highlighted the following case study:
Custom software development companies in Australia offer a broad range of services to help businesses streamline operations and amplify product value. Here are some of the most common offerings they provide:
While these standard services are prevalent, Australia’s diverse business market drives demand for other specialized solutions, such as AI development, blockchain solutions, and AR/VR applications.
While there is no exact data on the number of software development companies in Australia, the overall tech workforce has reached 935,000 employees in 2023, emphasizing the vastness of the industry. Our DesignRush listing features over 7,600 custom development firms, 280+ of which are based or have offices in Australia.
Here’s a breakdown of our featured agencies by company size:
| Agency size | Number of agencies |
| Small (Under 49 employees) | 133 |
| Mid-sized (50-249 employees) | 102 |
| Large (250+ employees) | 38 |
| Enterprise (1000+ employees) | 13 |
The dominance of smaller agencies can be attributed to the lower overhead costs and increased flexibility these firms offer. Mid-sized agencies, while fewer, handle larger projects that require more resources and coordination, making them an optimal choice between the smaller firms with limited capacities and larger agencies with higher service rates.
Australia software development firms charge between AUD 40,000 and 450,000+, depending on the project’s complexity, size, list of features, developer expertise, and timeline.
Some companies charge depending on the software development lifecycle (SDLC) phase, specifically:
| Development phase | Cost |
| Planning (Concept and feasibility analysis) | AUD 5,000-20,000 |
| Design (UI/UX design) | AUD 10,000-50,000 |
| Development (Frontend and backend) | AUD 50,000-300,000 |
| Testing | AUD 5,000- 30,000 |
| Deployment and maintenance | AUD 10,000-100,000 (annually) |

On the other hand, 4.2% of the agencies require a $50,000+ minimum budget, focusing on large-scale projects that require advanced technologies and extensive customizations.
