Our approach to social impact investment

Social impact investment (SII) is a form of impact investing that provides government with a different approach to addressing social issues in collaboration with the for-purpose (not-for-profit, social enterprises, philanthropy) and for-profit sectors (private investors), through a focus on outcomes.

OSII partners with other government agencies to commission innovative outcome-based programs. Outcome-based approaches include a range of investment structures where a part of the funding is dependent on the achievement of outcomes. These outcome-based contracts are also referred to as Payment-by-Results, Payment-by-Outcome, and Pay-for-Success.

A focus on outcomes supports innovation and provides flexibility to better meet the needs of the individuals receiving support. It also ensures accountability and helps to build an evidence base of what works. 

Our SII approach is supported by 4 core principles: 

Early intervention and prevention

Empowering people to improve the course of their life and reduce the need for avoidable government support.


Testing innovative services and building an evidence-base for what works.


Leveraging the strengths of different sectors and sharing risks and rewards. 


Designing, measuring, and paying for outcomes. 

How outcome-based contracts work

Outcome-based contracts enable risk sharing to incentivise innovation, collaboration and better services​.

Types of social impact investments 

Social impact investments come in many forms. We have facilitated the following types of social impact investments:

signing a contract
Payment-by-Results contract

Payment-by-Results (PBRs) are outcome-based contracts where a portion of funding is dependent on the delivery of outcomes. They can also be referred to as Payment-by-Outcome and Pay-for-Success contracts.

Family support
Social Impact Bonds

Social Impact Bonds (SIBs) also referred to as Social Benefit Bonds (SBBs), are a financing mechanism that enable service providers to enter outcome-based contracts with government. SIBs raise investor capital to fund service delivery costs and share in the financial risk of service providers achieving the agreed outcomes.

Calculating finance
Blended finance

Blended finance combines different types of capital (such as debt, equity and philanthropic funding).

We are open to exploring alternative impact investment structures. Contact us for further information.
